Pioneer P41 Diagnostic |

|
Hey so I just picked up a Pioneer P41 that was at an estate sale |
|
for $10. I really like the saw so I cleaned the carb and got it |
|
started today but theres a problem. I can't seem to tune the |
|
thing like it idles really high and if I turn it down it will |
|
just die but I can hold the gas and it will rev up but its |
|
reving up with like a slight bog. So it won't rev up all the way |
|
and it won't cut anything. I tried to cut some logs I had laying |
|
around and it would cut them at all and the chain is pretty much |
|
brand new so I have no idea whats wrong. The chain doesn't get |
|
stuck in the log it keeps spinning so I don't think its the |
|
clutch but idk. The only problem that I can spot is the fact |
|
that it has a black rubber O ring on the gas cap when it should |
|
be a cork O ring which might be causing it to lean out idk. And |
|
yes I tried putting both the high and low to one turn out but no |
|
matter what I put the screws on the thing idles terribly and |
|
will spin the chain because its idling so high. |

adjust your L screw about 1-1/4 turn out and H around 1-turn out |

The fuel lines and tank were actually perfect but I flushed the |
|
tank and lines anyways. |

|
my only other option would be a carburetor kit or some times |
|
there is a fuel filter inside the carburetor that gets some dirt |

Ok thanks for your reply but 1. Its not the carb. 2. I'm fairly |
|
sure its the head gasket. 3. Its impossible to tune but the |
|
thing runs so its not a typical fuel issue. |
|
So yea I'm pretty sure its the head gasket having a leak thats |
|
letting in air which means that this saw is going to become a |
|
parts saw unless I can find a new head gasket. |

I dont know saw. Head gasket and cylinder gasket the same? You |
|
can make your own cylinder gasket or leave them out and use |
|
threebond 1194 etc if you have squish clearance. |
|
Looking up to see what it is P41 |

The cylinder and head are one piece, no gasket. It sounds like |
|
an air leak, the best way to check it is with a pressure/vacuum |
|
tester which would pinpoint leaking crank seals, cylinder base |
|
gasket, intake gaskets. Check the insulator block behind the |
|
carburetor for cracks or warpage. |

I put soapy water on the cylinder base gasket and I can clearly |
|
see where its bubbling. When I said head gasket I actually meant |
|
cylinder base gasket but thanks for the replies! |
